Thrust test bench for student rocket engines

2016 11th France-Japan & 9th Europe-Asia Congress on Mechatronics (MECATRONICS) /17th International Conference on Research and Education in Mechatronics (REM), 2016
This paper describes a test bench for rocket engines for educational purposes and small research launchers. Students can develop their own propulsion systems and test them under realistic process conditions. The test bench is equipped for solid combustion as well as for hybrid engines with solid propellant and gaseous oxidizer.

Shelf-life analysis of solid rocket engine using HTPB/AP based on kinetic-chemical parameters of DSC analysis and burn on a test bench

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2019
Propellants based on HTPB/AP (hydroxyl-terminated polybutadiene/ammonium perchlorate) are the most commonly used in most of the rocket engines used by the Brazilian Armed Forces. This work aimed at the possibility of extending its useful life (currently in 10 years) by performing chemical kinetic analysis of the energetic material via differential ...
